WELL-BORING MACHINE.

SPECIFICATION forming part of Letters Patent No. 315,868, date-: April 14, 1885.

Application filed February 7, 1385. (No model.)

I is the well-tube, and a weight, J, is rig- 5o To all whom t may concern:

Beit known that I, WlLLnr C. lVnLLs, a citizen of the United States, and a resident of Tiftin, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in fell-Boring Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speciiication, and in which- Figure l is a side view of my improved well-boring machine, showing it in operation; and Fig. 2 is a horizontal 'sectional View on line :c fr, Fig. I.

Similar letters of reference indicate corresponding parts in both the figures.

My invention has relation to that class of machines for boring wells in which the drill is raised and thereupon dropped, acting by its own weight, and in whichthe well-tube is inserted into the bore, following immediately after the drill; and it consists in the improved construction and combination of parts of a machine in which the tube is driven into the bore by a weight secured rigidly to the drillstock, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A -indicates the base-frame of the machine, in which is journaled a windlass, B, which is continually revolved by any suitable machinery, and upon which frame the upright C iS secured, in the upper end of which upright a sheave, D, is journaled, over which sheave the drill-rope E passes, which rope passes around the Windlass a few times sufficiently to cause it to wind upon the windlass when the free end of the rope is tightened, while the rope may slip upon the drum of the windlass when the free end of the rope is slackened. lThe drill-stock F is tubular, forming the delivery-pipe, through which the water carrying the dbris ascends with the dbris, and a knee, G, is swiveled to the upper end of the stock and provided with a hose, H, which discharges the water and dbris.

idly secured upon the drill-stock by means of bolts K orsimilar means, being secured in such a manner that the weight may be adjusted at any place upon the drill-stock. In this manner it will be seen that the weight may u be adjusted upon the drill-stock so as to cause it to force the tube down at each stroke, striking the upper end of the same, and the bit may either reach below the lower end of the tube at the end of the downstroke, which is accomplished by adjusting the weight higher upon the drill-stock, which may be desirable in harder ground, or the bit may only reach to Within a short distance from the lower end of the tube, which is accomplished by adjusting the weight farther down upon the stock when the tube is driven through loose sand or similar ground, when it is desirable to allow a plug of sand to be formed in the lower end of the tube, so as to prevent the water which is' forced down through the tube outside of the drill-stock from rushing out too freely, which would 'be liable to happen in loose ground, and which would prevent the dbris from being carried with the water into the hollow drill-stock. By this construction it will be seen that the drill and tube are forced into the ground simultaneously, the tube either following the drill or the drill following the tube, according to the nature of the ground in which the machine works, the adjustment of the weight upon the drill-stock regulating the relative manner in which the drill and tube are driven into the ground.

I am aware that a weight has been placed so as to slide upon the drill-stock for the purpose of driving down the tube while the bore is being drilled; but this weight must be operated separately from the drill-stock, which simply serves as a guide for the weight to slide upon, and I do not wish to maire any claim for this construction; but

I claim- 1. In a Well-boring machine, the combina,- tion of a drill-stock having means for reciprocating it, and a weight secured rigidly and adjustably upon the said stock, as and for the purpose shown and set forth.

2. The combination of the Well-tube, the In testimony thatolaim the foregoing as my drill-stock having means for reciprocating it own I have hereunto affixed my signature in within the Well-tube, and a Weight secured presence of two Witnesses. rigidly and adj ustably upon the drill-stock, so W'ILLE'I C. WELLS.
